With 500 computers, the Gigabit Optical Fiber switch solution is required. Internet cafes need to support port mirroring, port aggregation, QOS, and other functions of the Gigabit Optical Fiber switch, to meet different network application requirements. Internet cafes with a large number of computers should also have other solutions. 300-about 500 Internet cafes The network center uses two RHS4624GMS fully Gigabit managed Ge Optical Fiber switches for 10 Gigabit cascade. It can provide 32 Gigabi

managed Internet cafe optical fiber switch. It provides 8 Gigabit SFP Optical Fiber ports, 8 independent 10/100/1000Base-T ports, and 48 Gbps backboard bandwidth, it can fully meet the network performance requirements of the entire Internet cafe. It also supports ARP security, port VLAN, and 802.1 QVLAN, Port Mirroring, port aggregation, QOS, and other functions to meet different network application requirements. 2. Eight

Optical fiber is generally made from Z (SiO2) after special pulling process. It no longer uses electronic signals to transmit data, but uses optical pulse to transmit signals, it features high bandwidth, large transmission capacity, low signal loss, and long transmission distance. Therefore, the emergence of the Internet cafe Optical Fiber solution will undoubtedly bring a spring breeze to the entire Internet cafe. The development of the Internet cafe industry has gone through countless leaps an

What are the differences between VCC, VDD, and VSS in electronic circuits? I. Explanation VCC: c = circuit indicates the circuit, that is, the voltage of the access circuit; VDD: D = device indicates the working voltage inside the device; VSS: S = series indicates the public connection, which usually refers to the public grounding terminal voltage of the circuit. Ii. Description 1. for digital circuits, VCC is the power supply voltage of the circuit, VDD is the operating voltage of the chip

motor drivers are integrated with charge pumps, it should be noted that the appropriate external capacitor should be selected to obtain sufficient short-circuit current to drive the MoS tube. 4. Enhanced and depleted type Mos-fet We often use enhanced mos-fet. Enhanced Mos-fet in the case of the gate without voltage is turned off, only when the VGS meet the open
